You can install Windows 11 manually on unsupported PCs.
seems that the Secure Boot / TPM 2.0 requirement will only be enforced if you try to upgrade from Windows 10. if you create an ISO and install manually, you won't have any problems. they also added some more CPU to the approved list, but doubled down on no Zen 1 support at all. they say that doing tests on Zen 1 based systems, they had 52% higher kernel crashes and the minimum spec is .02% or better.
any thoughts on why Zen 1 would have so many issues???
